Dr. Holland’s research currently focuses on pediatric neuroimaging applications of MRI, MEG and EEG methods; including perfusion MRI, functional MRI, and image processing methods, to study development of the neural circuitry of hearing, language, speech and reading capabilities through childhood. His discoveries regarding changes in brain activity and connectivity during typical childhood development and under the influence of neurological disorders have been influential in our understanding of neuroplasticity and reorganization of the developing brain in response to injury.
